Hello everyone,
The following question was recently given to a case-buddy of mine in a first-round interview at one of the top-tier firms: “What is the value of superman? (as a fictional character)”. For my analysis I proposed the issue-tree below, which is close to what my buddy had proposed in his interview. However, the interviewer did not seem completely satisfied with this structure. How would you go about this case?
